ATWINC1500-XPRO

Single Chip IEEE 802.11 b/g/n Network Controller SOC with Integrated Flash Memory

Atmel Corporation 

6. CPU and Memory Subsystem

6.1 Processor

The Atmel WINC1500 device has a Cortus APS3 32-bit processor with a JTAG debug interface. This processor

performs many of the MAC functions, including but not limited to association, authentication, power

management, security key management, and MSDU aggregation/de-aggregation. In addition, the processor

provides flexibility for various modes of operation, such as STA and AP modes.

6.2 Memory Subsystem

The APS3 core uses a small boot ROM along with a 128KB instruction RAM and a 64KB data RAM. In addition,

the device uses a 128KB shared memory which allows the APS3 core to perform various data management

tasks on the TX and RX data packets.

6.3 Non-Volatile Memory

The Atmel WINC1500 device has 256 bits of non-volatile memory (NVM) that can be read by the CPU after

device reset. This non-volatile one-time-programmable (OTP) memory can be used to store customer-specific

parameters, such as the MAC address, along with calibration information, such as TX power calibration tables.

6.4 Flash Memory

NMC1500 has 4 Mbits of Flash memory that can be wrote to and read by the CPU. This memory can be used to

store the Network IP stack (TCP, UDP etc) and Wi-Fi Security such as WEP, WPA(2) and WPS. Enables host

driver to operate on very small memory footprint MCUs without an OS (4KB Flash/1KB RAM).
